IRS2580DSTRPBF

Overview

The IRS2580DSTRPBF is a Power Factor Correction (PFC) controller IC manufactured by Infineon Technologies, designed for Critical Conduction Mode (CRM) applications. It operates within a supply voltage range of 11 V to 18 V and features an 8-SOIC package. The component supports high-efficiency power conversion with integrated protection mechanisms suitable for compact power supplies.

Feature Summary

• Supports Critical Conduction Mode (CRM) operation for optimized PFC performance
• Integrated bootstrap diode for simplified high-side driver implementation
• Compact 8-SOIC surface-mount packaging for space-constrained designs

Applications

• Critical conduction mode power factor correction circuits
• High-efficiency AC-DC power adapters
• LED lighting drivers requiring PFC compliance

Procurement Notes

Verify the exact suffix DSTRPBF against official Infineon documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through current datasheets as regulatory requirements may change. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when CRM topology is required for medium-power PFC applications. Compare propagation delays and switching frequencies against alternative controllers if specific timing constraints exist. Validate thermal performance in the target enclosure before finalizing the design.

Part Context

This part belongs to Infineon's IRS25xx series of power management ICs. It complements other gate drivers and controllers in the portfolio by focusing specifically on CRM PFC solutions. The SOIC-8 package aligns with standard industrial footprint requirements for similar control ICs.
